Hi Ray,

Yeah, it looks like Joshua Pollack ran into this issue three years ago:

    http://mail.python.org/pipermail/tutor/2002-September/017579.html

I'm going through the archive now to see if he was able to resolve the
problem ok.

You might also want to bring this up on the gnuplot-py-users mailing list:
I'm sure that they'd definitely know what was going on:

    http://lists.sourceforge.net/lists/listinfo/gnuplot-py-users

In the meantime, I'll continue to do some hunting in the mail archive.
*grin*

Good luck to you!
